PI49FCT3805SE

Clock Buffers, Drivers Overview

The PI49FCT3805SE is a 3.3V non-inverting clock driver manufactured by Diodes Incorporated in a 20-pin SOIC package. It features two independent buffer groups, each with a 1-in, 5-out configuration and active LOW 3-state Output Enable inputs (OEA, OEB). The device provides extremely low output skew of 0.5ns and includes a dedicated monitor output pin for diagnostics. It operates within an industrial temperature range of –40°C to +85°C and supports TTL input and CMOS output compatibility.

Clock Buffers, Drivers Feature Summary

• Two independent 1-to-5 buffer banks with 3-state control
• Extremely low output skew: 0.5ns
• Dedicated monitor output pin for diagnostics
• TTL input and CMOS output compatible

Clock Buffers, Drivers Applications

• Clock bus distribution with 3-state control
• High-speed clock distribution requiring low skew
• Single point-to-point transmission line driving

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'E' indicates Pb-free and Green packaging status as specified in the datasheet. Confirm the speed grade corresponds to the blank suffix variant. Ensure the 20-pin 300-mil wide SOIC package matches the design requirements.

Clock Buffers, Drivers Selection Notes

Select this component when a non-inverting clock driver with 3-state outputs is required. The PI49FCT3806 should be chosen if an inverting configuration is needed instead. Consider the specific speed grade (Blank, A, B, or C) based on propagation delay requirements.

Clock Buffers, Drivers Part Context

This part belongs to the PI49FCT series of Fast CMOS logic circuits produced using advanced submicron technology. It serves as the 3.3V version of the PI49FCT805/806 family, designed for high-speed applications where signal quality and skew are critical.
